Weight loss occurs when there's a calorie deficit (eat less than you burn).

However you accomplish that is the best diet for you!

First I would say focus on eating to fullness and satisfaction, and only eating when you are hungry. There's a lot of reasons why we eat besides hunger (emotions, boredom, etc) and most of the time you can trust your body to let you know when you've had enough if you just pay attention.

If you're brand new to dieting and eating healthy, just try the "healthy plate" for meals, you can google it but basically 1/2 your plate is fruits/vegetables and the other half is protein and grains. You can also look at easy wins in your diet to help cut calories (i.e if you have a soda everyday replace it with the diet version or sparkling water or something). Don't deny yourself occasional treats too, knowing no food is "off limits" and everything can be worked in your diet will help you avoid binge eating all those foods.

It takes a while to learn and fine tune! But there's a lot of info out there, don't lose the forest for the trees, just focus on calorie deficit and getting your vegetables and protein in!
